Description
Technical Field

Background
The escalator is widely applied to places with large pedestrian flow, such as subway stations, shopping malls, pedestrian overpasses and the like. The escalator operates for a long time once being started, so that the energy consumption is high, and the energy-saving space is relatively large. If the system can realize normal operation in busy hour, slow operation in idle hour even stop operation and automatic starting operation when passengers are waiting, the electricity can be greatly saved.
The self-starting sensing device of the traditional escalator usually adopts a photoelectric or ultrasonic sensing mode, when a passenger arrives, the sensing device senses the body of the passenger to generate a sensing signal and converts the sensing signal into an electric signal, so that the slow or stopped escalator is put into operation again. However, due to the limited structure of the escalator, the sensing probe of the sensing device is often arranged at the handrail device which is close to the steps, which causes the response time of the self-starting sensing device to be very short, and even after the passengers step on the steps, the escalator starts to start and accelerate. It is a very dangerous situation that a passenger stands on a step to start and accelerate an escalator, because the passenger often has no time to grasp a handrail belt, so that the danger of falling backwards is generated, and thus, a serious potential safety hazard exists.
For example, 11/2016, a company accident happens in Wuyue square in Qingpu area of Shanghai, and when milk holds a baby boy for only 4 months in the year, the baby boy just walks onto the escalator, the self-starting sensing device is started, the milk reaction is not timely, the body is inclined out of control, the baby boy breaks away from the milk hand, falls from 3 th, and is rescued inelessly to die after being sent to a doctor.
